When was solar energy invented?
The development of solar cell technology, or photovoltaic (PV) technology, began during the Industrial Revolution when French physicist Alexandre Edmond Becquerellar first demonstrated the photovoltaic effect, or the ability of a solar cell to convert sunlight into electricity, in 1839. [2] About four decades later, American inventor Charles Fritts created the world’s first rooftop solar array in New York in 1883, one year after Thomas Edison opened the world’s first commercial coal plant. [3] Fritts coated the panels with selenium to produce a very weak electric current. However, the process of how light produces electricity wasn’t understood until Albert Einstein wrote a paper explaining the photoelectric effect in 1905, [4] which won him the Nobel Prize in physics in 1921. [5] Becquerellar’s and Einstein’s research formed the basis of future developments in solar technology.

How does solar energy work?
Solar energy is a photovoltaic effect. It is the act of electricity generated from sunlight. Sunlight begins with the sun. The sun is made up of four layers which are: the core, the radiative zone, the convective zone, and the photosphere. These layers have their own purposes that creates light. Light is a form of radiation, electromagnetic radiation, which is made up of photons. The core produces the energy by hydrogen atoms (H). Then it converts to nuclei of helium. The temperature of the sun is 5,778 Kelvin (9940.73 Fahrenheit) because of how much pressure it has. The pressure creates Nuclear Fusion which is what creates heat and light. After the light is created, it travels as both waves and particles. Light also does not need the help of matter to travel throughout space. The distance between Earth and the Sun is 92.96 million miles away. It takes eight minutes and twenty seconds for light to reach Earth even at the speed of light!

How did the Nebular hypothesis work?
The Americans Thomas Chrowder Chamberlin and Forest Ray Moulton and later James Jeans and Harold Jeffreys of Great Britain developed variations on the idea that the planets were formed catastrophically—i.e., by a close encounter of the Sun with another star. The basis of this model was that material was drawn out from one or both stars when the two bodies passed at close range, and this material later coalesced to form planets . A discouraging aspect of the theory was the implication that the formation of solar systems in the Milky Way Galaxy must be extremely rare, because sufficiently close encounters between stars would occur very seldom.
